Title: Low input impedance type broad-band preamplifier
Inventor: KOYAMA YASUSHI
IPC: H03F3/34
Filed: 1981-08-11
Abstract: PURPOSE:To improve the stability of a DC output voltage for the entire amplifier, by constituting the amplifier through the use of a pair of complementary transistors (TR), and a pair of TRs cancelling each temperature characteristic and temperature compensating elements. CONSTITUTION:When an input currentIi is given to an input terminal 11, the emitter potential of a TRQ1 is increased, the base current of the Q1 is decreased and the collector curent is decreased to increase the collector potential. Then, a base-to-emitter voltage of the Q2 is decreased and the base current is decreased. Thus, a collector current multiplied by beta flows to the collector of the Q2 to lower the collector potential. On the other hand, since the emitter potential of the Q3 is made equal to the emitter potential, the potential is increased. Thus, the potential difference between the base and emitter of the Q3 is accumulatively increased and the base current of the Q3 is increased. Then, the collector current multiplied by beta flows to the collector of the Q3 and is outputted as an output signal from output terminals 13 and 14.
